  • an optimum recording power can be obtained under the same condition as that when performing an information recording operation. Thereby, a stable recording quality can be maintained when performing information recording according to the constant linear velocity using the optical disc 100 having a recording layer of a multilayer structure.
  • a rotation speed must be increased as a recording point goes further inner side when the CLV method is used, it may become difficult to rotate the optical disc at such a high speed.
  • a motor cost may be increased so as to provided a spindle motor that can achieve a higher rotation speed, and an increase in the rotation speed may increase noise and vibration. Additionally, it may become difficult to design the servo system.
  • measures may be taken to limit a decrease in the rotation speed on the outer side. That is, in such a case, the linear velocity increases toward the outer side. Therefore, as explained in the first embodiment, a result of an OPC at the outer side and a result of an OPC at the inner side are acquired so as to set a recording power at an intermediate linear velocity as an optimum recording power of the optical disc 100 .
  • the present invention is applied to a desk-top type personal computer 50 , which is equipped with the optical disc drive apparatus 1 such as explained in the above-mentioned embodiments in addition to a 3.5-inch flexible disc drive apparatus 51 .
  • the optical disc drive apparatus 1 may be integrally incorporated in the personal computer 50 , or may be a built-in type. Accordingly, a host is also incorporated in the personal computer 50 .
  • the optical disk drive apparatus 1 Since the above-mentioned optical disk drive apparatus 1 is built in the personal computer 50 , the optical disk drive apparatus 1 , which can acquire an optimum recording power in an OPC operation during a information recording operation according to the constant linear velocity method or the constant angular velocity method using the multilayer optical disc 100 having the two-layer recording layer, can be used as a memory apparatus of the personal computer 50 .
  • the optical disc drive apparatus is not limited to be built in the personal computer 50 as in the present embodiment, and may be provided alone and connected to an information processing apparatus such as an external host apparatus.
  • the personal computer 50 is not limited to the desk-top type, and a portable type personal computer such as a notebook type computer may be used.
  • a program that describes the above-mentioned optical information recording method may be stored in a processor readable medium such as a CD-R or a flexible disc so that the personal computer 50 can perform the function according to the information recording method by loading the processor readable medium to the personal computer 50 as shown in FIG. 7 .
